PAPER-FASTENER.

SPECIFICATION forming part of Letters Patent No. 693,302, dated February1 1, 1902.

Application tiled August 2l, 190.1. Serial No. 72,757. (No modelnew andimproved paper-fastener which is simple and durable in construction,easily applied to fasten a desired number of superimposed sheetssecurely together, and to provide an eyelet for the passage of aseal-ribbon for sealing the papers.A

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

A practical embodiment of the invention is represented in theaccompanying drawings,l

forming a part of this specication, in which similar characters ofreference indicate corresponding parts in all the views.

Figure lis a rear face view of superimposed sheets with the front memberof the fastener shown in dotted lines in position. Fig. 2 is a rear faceview of the sheets with both members of the fastener in position. Fig.Sis a like view of the same with the partsin a different position. Fig.4 is a like view of the same with the members of the fastener securelylocked together. Fig. 5 is an enlarged sectional elevation of theimprovement on the line 5 5 of Fig. 2, and Fig. 6 is a perspective viewof the front member.

The improved paper-fastener consists, es-

sentially, of the members A and B, made of sheet metal or other suitablematerial, and between which the' superimposed sheetsO are held andfastened together, as hereinafter more fully explained. The member A ispreferably used on the front face of the superimposed sheets, and ishence the front member, while the other member is applied to the back ofthe superimposed sheets. The front member A is provided at diagonalcorners with pins D, adapted to pass through the superimposed sheetsGand through registering apertures E, formed in the rear member B, as

plainly indicated in Fig. 5. The pins D are bent onto the outer face ofthe back member B, the bent-over portions of the pins extendinglongitudinally parallel to each other, as plainly indicated in` Fig. 3,and in order to conceal the pins and to lock the samein place aps B',extending integrally from the rear memberB, are bent over onto thesaidpins, as plainly indicated in Fig. 4. The front member A is provided ator near its middle with an aperture A', registering with asimilaraperture B2, formed in the rear member B,"and the side edges of theflaps B' are formed with cut-out portions B4, so that when the flaps arefolded over the pins, as previously explained, then the said iiaps donot cover up the aperture B2, as the cut-out portions B4 registerv withthe aperture. Thus a seal-ribbon may be readily passed through thefastener whenever it is desired to seal the papers, it being understoodthat the paper material of the sheets E extending in the apertures caneither be punched out previous to applying the fastener or it may bereadily cut out by a knife or other suitable tool after the fastener isapplied. In order to prevent the pins D from being accidentally bentover the apertures B2, I prefer to form on the outer face of the rearmember B an annular boss or projection B3, surrounding the aperture B2and forming a guard for the pins D. The boss B3 is otabout the sameheight as the thickness of the pins D, so that when the flaps B arefolded upon the pins the boss does not project beyond the outer faces ofthe flaps.

In using the device the front member A is pressed against thesuperimposed sheets C, so asto cause the pins D to penetrate the sheets,and then the rear member B is engaged with the pins on the back ofthesheets, after which the pins are bent over, as described. Then the iiapsB are folded upon thel pins to conceal andlock the same. The papersarenow securely clamped between the members A and B. v

The device is very simple and durable in construction, can be verycheaply manufactured and readily applied, and whenever it is desired todisconnect the superimposed sheets the user can readily bond thctlaps Bback to their original position and then bend the pins back and separatethe members A and B from each other.

As the pins D are completely concealed, it is evident that they cannotcatch on other papers or other articles with which they come in contact.g

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. A paper-fastener comprising two members, of whichone is provided with pins for passing lthrough the papers and forengaging the other member, the said members having registering aperturesfor the passage of a sealribbon, and fiaps on the other member forconcealing and locking the pins without covering the registeringapertures, as set forth.

2. A paperfastener, comprising a front member having a plurality ofpins, a rear member having apertures for the passage of the pins, andiaps extendingintegrally from the said rear member for folding over thepins to conceal and lock the pins in place, the rear member having aboss for guiding the pins into a bent position, as set forth.

3. A fastener comprising a member provided with pins and with aribbon-receiving aperture, and another member provided with perforationsarranged similarly to the pins on the first-named member and alsoprovided with a ribbon-receivin g opening, whereby the members maybeassembled 'for the pins to pass through the perforated member and theribbon openings of the two members are brought into registeringrelation.

4. A fastener comprising two members each having a ribbon-aperture, andmeans for positively locking or uniting said members together, wherebythe apertures in said members may be brought into registration andadapted to receive a fastening-ribbon.

5. A fastener comprising a member having pins and a ribbon-opening,another member provided with apertures and with a ribbonopening, andbendable aps projecting from the last-named member and having notchesarranged, in the bent positions of the aps, to lie coincident with theribbon-opening in the member.

6. A fastener comprising a member having pins projecting from diagonalcorners thereof, and also having a ribbon-aperture, another memberprovided with pin-apertures and with a ribbon aperture, and flaps on thelastnamed member adapted to be individually bent into locking engagementwith the ends of said pins when the latter are bent onto tho last-namedmember.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses. v 4
